Resistance
It is important to understand how the resistance
of different leadout wires can affect the
performance of your electric fence.
Resistance (Ohms) measures a wire’s ability to
conduct electricity (current). The lower the Ohms,
the more current it will conduct. It has the same
effect as the friction of a water pipe has on water
flow. Voltage in electricity is like pressure in water.
Electric current (amps) is like water volume or
flow.
4.4 Fence Construction
4.4.1 Install the leadout
The leadout cable is the power link
between the Energizer and the fence.
The leadout cable can be either run
overhead or underground.
Insulated leadout cable should be
used to prevent the leadout from
shorting out on obstructions or the
ground.
